Remove the Open File Security Warning in XP, Vista, and Windows 7

February 20th, 2009 Leave a comment Go to comments

Every single time you download a program and try to run it, that stupid pop-up comes up and adds a whole extra click. The pop-up looks like this:

"Open File - Security Warning" - "The publisher could not be verified. Are you sure you want to run this software?" YES I'M SURE DAMNIT!

"Open File - Security Warning" - "The publisher could not be verified. Are you sure you want to run this software?" YES I'M SURE DAMNIT!

You can remove this in any Microsoft OS that is XP or later with the same steps. How do I remove this you ask? Like so:

1. Click Start, Run (or Windows+R) and type gpedit.msc


2. Navigate to User Configuration -> Administrative Templates -> Windows Components -> Attachment Manager
then double click “Inclusion list for low file types” on the right pane

Group Policy


3. Select Enabled and enter in the file extensions you want to allow, including the preceding period and separated with a semicolon


Inclusion list for low file types

Hit OK, exit out of your Group Policy window, and run your newly downloaded spyware infested program, free of the annoying “security” pop-up!

    Thank-you this worked great with the addition of one extra step … my XP SP3 installation, for whatever reason, didn’t have an Attachment Manager policy installed … to add the Attachment Manager Policy, right click on Administrative Templates … select Add … enter system.adm then open … this adds the required policy … then just continue with step 2. Again Thank-you for this information

    I was trying all these complicated methods when all the *.exe file needed was a zip and unzip… it strips it of metadata type stuff that your browser tags on to it…
